BURNER.

Specification of Letters Patent.

Patented Dec. 25, 1906.

Application filed July 17. 1903. Serial No. 166,033.

To all whmn it may concern:

Be it known that I, ARTHUR B. CLUNIEs, of Rochester, in the county of Monroe and State of New York, have invented certain new and useful Improvements in Burners; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming a part of this specification, and to the reference-numerals marked thereon.

My present invention relates to improvements in burners particularly adapted to use gaseous fuel, and it has for its object the production of a burner of this character wherein the particular arrangement and disposition of the emission-orifices and their relation to the air-supply passages is such as to secure a higher percentage of combustion, and also to provide a peculiar formation of the mixing or commingling chamber to insure a thorough mixture of the air and gas, and also to eliminate or reduce to a minimum the explosion in the mixing-chamber ensuing after theinterruption of the fuel-supply.

Other features of novelty and advantage will be hereinafter more fully described, and pointed out in the claims hereunto annexed.

In the drawings, Figure 1 represents a plan view of a burner embodying my said inven tion. Fig. 2 represents a central longitudinal section of the same, and Fig. 3 is a transverse sectional view on the line 3 3 of Fig. 1.

The same numerals of reference designate similar parts throughout the views.

In the present embodiment of my invention 1 designates the body of the burner, formed in any suitable manner and provided with the hollow extension 2 and the supportinglug 3. These parts may be formed integrally, or, if preferred, may be made separately and secured together in any suitable manner. The device shown embodies a hollow casing 1, forming the commingling or mixing chamber, through which extend a plurality of air-supply passages 4 l. These passages extend entirely through said casing and terminate on the upper surface thereof, and around the outlet of each passage is formed an elevated ridge 5, each of which is provided with a plurality of orifices 6 6, communicating with the chamber 7. A similar ridge Sis also formed on the peripheral edge of the upper surface of this casing, and provided with similar perforations or orifices 9 9, also communicating with the chamber 7.

Extending inwardly from the outer ridge 8 and disposed around and between each of the ridges 5, surrounding the passages 4, are depressions 1O 10, forming air ducts or channels leading from the air-supply passage 11, perforating the casing.

By such an arrangement it will be understood that the mixed or commingled supply of gas and air issuing from the orifices 6 6 of the ridges 5 5 will be fed during combustion with air from the passages 4 4 at one side and on the other side with air from the air-ducts 10 10, fed from the passage 11. flame from the orifices 9 in the peripheral ridge 8 of the casing will be supplied on one side with air from the exterior of the casin and at its inner side from the air-ducts 10 and the air-passages 4. It will thus be seen that the relative disposition and arrangement of the orifices and the air-feeding passages is such that the flame from each orifice is fed with air at all sides and that the arrangement and disposition of said passages 4 and 11 within the mixing-chamber 7 is such that a thorough commingling of the gas and air is effected, producing a better combustion, and consequently increasing the efficiency of the burner, and that the formation of said chamber and the disposition of said orifices are such that the mixed gas will escape through said orifices with the utmost freedom. Therefore when the supply of fuel is interrupted the gas will freely escape through said orifices without lingering in the mixing-chamber to form an explosive mixture with the air rushing in through the mixing device 12, located in the path of the fuel-supply. Such explosions are common in burners of the class com monly known as central-draft" burners but by the construction hereinbefore described I have eliminated or reduced such explosions to a minimum.

The casing or body portion 1 of the burner may be conveniently formed in one integral piece, as shown, or, if desired, may be made up of several parts secured together, a cover formed separately and secured to the body portion or casing being found advantageous in some instances.

Other changes and arrangements of the parts may also be made in said invention The jets of" air-passage without departing from the spirit thereof, it

, provided with a series of annular ridges, one

surrounding each air-passage of said row, and each havmg a plurality of or1fices formed therein and communicating with the mixingchamber, the depressions formed between said ridges communicating with said central 2. A burner comprising a hollow casing having a row of annular ridges formed in the top thereof forming ducts between them and having a series of orifices communicating with the mixing-chamber, an annular row of air-supply passages being extended through the casing and each discharging on the top thereof at the inner side of its respective ridge, a central passage extending through the casing and communicating with said ducts for feeding air to the outer sides of the ridges.

3. A burner comprising a hollow casing having a mixing-chamber formed therein, an annular row of ridges formed in the top of the casing each provided with a series of orifices which communicate with the mixing-chamber, walls forming air-supply passages extending through the casing and discharging at thetop thereof within each row of orifices, a peripheral ridge on the top of the casing outside of the row of ridges having orifices formed therein communicating with the mixing chamber, an air passage extending through the casing within the row of ridges for supplying air to the orifices at the outer sides of the row of ridges and at the inner side of the peripheral ridge.

4. A burner comprising an integrallyformed casing having a mixingchamber therein, thetop of the casing being provided with an annular row of spaced ridges each having a series of orifices therein communieating with the mixing-chamber, a tubular extension connecting the top and bottom of the casing and extending through the mixing-chamber forming an air-supply passage for each series of orifices, a peripheral ridge formed on the top of the casing provided with a series of orifices communicating with the mixing-chamber, air-supply ducts formed in the surface of the-casing between the ridges in said row leading to the orifices of the ridges from central air-supply passage extending through the casing.
